Application filed April 29, 1903, Serial No. 154,876.

To all whom it may (on/007w.-

Be it known that I, FRANK HrNuxN Pum- PONT, a citizen of the United States, residing temporarily at Horley, county of Surrey, England, have invented certain new and useful Improvements in Standardizing or Meas uring Machines for Matrices; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to a machine or apparatus for standardizing or measuring objects, such as matrices, punches, type, 620.,

where accuracy of form and position are of consequence, and has for its object to provide a means whereby the position and dimensions of the character, be it intaglio or cameo, can be readily and accurately determined in two or more planes-that is, in the plane of the surface of the matrix-block and in the plane of the surface of the character, either at the extreme depth of the cavity or at the extremity of the punch or type.

The present embodiment is especially adapted for standardizing the matrices for type-casting and similar machines and comprises as its principal elements a magnifying apparatus provided with a fixed objective and adapted either for direct vision or projection upon a screen, a standard pattern or scale, a vertical illuminator or prism, a blank or matrix carrier, and means for positioning the blank or its carrier so as to present the character in two fixed positions relatively to the objective, so that two sections of the ar ticle to be standardized will be successively presented in truefocal relation thereto. Thus in the case of a matrix the surfaces at opposite extremes of the matrix-cavity will be successively presented in true focal relation to the objective. Devices are also provided for facilitating the feeding and removal of the matrices and for ejecting those found to be defective.

In the accompanying drawings, illustrating the preferred embodiment of the said invention, Figure 1is a front elevation, and Fig. 2 a side elevation, of an apparatus arranged for direct vision. Fig. 3 is a longitudinal sectional view of the optical part. Fig. 4 is a sectional view, and Fig. 5 an end view, of a matrix shown on an enlarged scale. Figs. 6 to 1.0, inclusive, are diagrammatic views illustrating the matrix and its actuating mechanism in different positions during 'the measuring and storing operations. Fig. 11 is a plan view of the holding-die detached. Fig. 12 is aside elevation, and Fig. 13 is atop plan view, partly in section, of a modified form adapted for projection as distinguished from direct vision. Figs. 14 to 17, inclusive, are diagrammatic views of the matrix adjusting and feeding devices in different positions. Fig. 18 is a horizontal section on line A A, Fig. 2.

Similar letters designate like parts in the several figures.

The matrices upon which this machine is specially designed to operate are represented in Figs. 4 and 5, wherein A is a rectangular piece of metal, preferably bronze, with a hole A extending transversely therethrough for the reception of the sustaining-rod. The letter-cavity A is driven or otherwise formed in one end of the blank, and in the exampleillustrated it represents the letter O. A is the matrix-end surface, and A the charactersurface, constituting the two surfaces with reference to which the measurements or comparisons are to be made. The principal dimensions or measurements required are indi' cated by the small letters a, b, c, d, e, andf in Figs. 4 and 5.

Referring specifically to the form of embodiment represented in Figs. 1., 2, and 2, a form adapted for direct vision, a frame is provided comprising a base C, with a vertical standard C" provided with a tubular portion C for the reception of a tube B, the latter forming part of a microscope and carrying the objective B in fixed position. A ove the objective is located a prism B for vertical illumination, to which end it is placed opposite openings C B in the frame and tube, respectively, said prism being so constructed and arranged that only those rays of light falling on a surface or surfaces at right angles to the optical axis will lie reflected to the eye. Hence only those surfaces of the matrix to be observedvl. 6., the end of the blank and the bottom of the characterare made visible to the operator. The ocular comprises a field-lens B and an eyelens and is furnished with a slide B, upon which is marked the necessary scales or pattern. The distance between the ocular and objective being 'fired, adapting-lenses, of which one, B, is shown, are provided to adapt the instrument to eyes of varying vision. Several of these lenses, both plus and minus, varying l-y e en dioptics, are usually supplied with each instrument. Beneath the objective and supported in horizontal guides or ways in standard C is a stop or gage plate D, of which the under surface, or that which contacts with the matrix, is at such a distance from the objecti e as to be in the exact focus of the microscope. In the plate D is formed an aperture D slightly smaller than the end of the matrix, so that when the latter is advanced into contact with the plate opposite said aperture it will be positioned with its surface in perfect focus and for the most part exposed to view. Adjacent aperture D is a second aperture D whose lower portion is enlarged to form a shoulder D, the depth of said enlargement being exactly equivalent to the depth of the character-cavity A of the matrix, Figs. 4. and 5. Consequently, when the matrix is advanced into contact with the shoulder D the bottom surface A of the matrix-cavity will be brought into focus. Thus the plate D constitutes a gage for locating the matrix with either of the two surfaces in exact focus. The plate D is held normally with the aperture D opposite the objective by a spring D encircling a pin D, carried by'said plate and interposed between the latter and a part of the frame.

The apparatus thus far described constitutes an efficient means for effecting the two measurements described, the matrix being manipulated by hand and held in contact first with one and then with the other gagingsurface, the plate D being shifted for the purpose; but by preference the apparatus is provided with automatic means for effecting the successive presentations, as will presently appear. V

In the standard A immediately below the normal position of the aperture D in gageplate D is a guideway C for the reception of the matrix-carrier E, whose upper end is offset and provided with a horizontal pin E, adapted to form a working fit in the matrixperforation A. The offset end of the carrier is preferably narrower than the matrix to allow an ejector, hereinafter described, to pass by it and engage the matrix. To insure the accurate presentation of the matrix against the surfaces of the gages, the upper section of the guideway C immediately below gage-plate 1) is preferably formed in an inserted die K F 11, accurately shaped to receive the offset portion of the matrix-carrier and the matrix.

The carrier Eis connected to a lever E pivoted at E to an extension of the standard C and having its outer end curved upward and provided with a guide to recei e a pusher E, which latter is furnished with a handle and a retracting-spring E The movement of the pusher is limited'by a pin E, working in a slot E and said pin projects into the plane of movement of an arm F, pivoted on lug C The arm F is held by a spring F normally in contact with a stop F Located one above another and to one side of the guideway C, with which they communicate, are two ways or slots G G, forming, respectively, the feeding and the receiving galleys for the matrices. Mounted to reciprocate in ways in the standard and in line with galley G is an ejector H, provided with a spring H for holding it normally retracted out of the way of matrix-carrier E, the engaging end of said ejector being furcated to pass on opposite sides of the offset end of the carrier E and engage the matrix held thereon on both sides of said offset. A pusher K, Figs. 1 and 2, provided with a retractingspring K and arranged to reciprocate transversely of the galley G near the receiving end, is provided for ejecting the last matrix delivered to the galleys should it be found defective.

The operation of the matrix-feeding devices will be best understood in connection with Figs. 6 to 10, inclusive. At the commencement of a cycle of operation the parts are as represented in Fig. 6, with the lever E and attached carrier retracted, the gageplate D in normal position, and the feedinggalley charged with matrices, of which latter the innermost one has been advanced onto pin E of the carrier. The operator grasping the end of pusher E raises lever E and carrier E until the end surface of the matrix on pin E is brought into close contact with the under surface of gage-plate D directly beneath aperture D During this movement the pin E, carried by pusher E, engaging the under edge of arm F forces the latter back against the pressure of its spring (the spring B being stronger than spring F and passes above, when arm F returns against its stop F and the parts assume the positions represented in Fig. 7. The operator now proceeds to make his readings or comparison with reference to the surface A of the matrix which is now in focus and illuminated. Having finished these readings, the operator advances the pusher E to shift the gage-plate D until its orifice D is brought into position and slightly elevates lever E thereby bringing the matrix into the position represented in Fig. 8, with its end surface in contact with the second gage D and the surface A at the bottom of the drive or matrix cavity in focus, whereupon the second set of readings or comparison is made. The usher E is new low ered slightly sufficiently to withdraw the matrix from gage-plate D and is then retracted until its pin E stands above the top of arm F, which latter serves to arrest the pusher opposite the ejector H and the carrier with its matrix opposite the pusher and in line with the receiving-galley G, as seen in Fig. 9. The pusher is now pressed forward, advancing the ejector, to discharge the matrix into galley G and at the same time carrying pin E beyond arm F, as seen in Fig. 10, whereupon by a further downward movement of the pusher the parts are returned to the position indicated in Fig. 6 ready to receive and present the next succeeding matrix. Should the matrix on inspection be found not to be of standard dimensions, it can be expelled from the receiving-galley by means of pusher K.

The apparatus thus far described illustrates but one of many forms in which the principle of the present invention may be embodied, said principle involving as its distinguishing features the employment in connection with a magnifying instrument of gages for locating successive and predetermined sections of the matrix in fixed relation to the objective, so that the measurements or comparison with the standard patterns may be made in parallel planes, and this whether the fixed relation of the objective and matrix with respect to the gages is made effective by a movement of either of said parts-that is, whether the objective is moved to the gage, the matrix being fixed, or the matrixis moved to or by the gage, the objective being fixed, or both the matrix and objective are moved to or by the gage.

The modification shown in Figs. 12 to 17, inclusive, illustrates an embodiment of the invention wherein a projecting apparatus is substituted for the direct-vision instrument or microscope of the previously-described form, and the gaging devices operate through the matrix-carrier instead of directly upon the matrix in adjusting and determining the latters position. For convenience the apparatus is disposed horizontally instead of vertically, the objective B being supported in a lug L of the frame L. Supported on a standard M in line with and in front of the objective is a tube M, (preferably rectangular in cross-section, about six feet in length, and in shape a hollow truncated pyramid,) within which and near the larger end is arranged a screen M, of ground glass or other appropriate material on which the scales or patterns are ruled or with which they are associated. The matrix-carrier E, with offset and pin E,

is mounted in guides on a plate L in which latter are also formed the feeding and receivin galleys G G. An equivalent form of vertical illuminator is interposed between the ma= trix-carrier and objective, (represented by a mirror N with central opening N The matrix-carrier E is furnished with a pin 0, engaging a cam-groove O in a block 0, the latter mounted to reciprocate 1n guides on plate L This cam-groove 0 serves both as actuator and gage for the matrix-holder and is so shaped that at each complete movement of the block 0 in either direction it places the matrix-carrier in four different definite positions for purposes hereinafter explained. The block 0 is reciprocated by an arm 0 of which one end is pivotally carried by a bolt 0', mounted on an extension L of the cover of block 0. In the other end of arm 0 is a slot 0 in which is engaged a pin 0, carried by block 0 and passing through a slot L in plate L Movement is imparted to arm 0 through a rod 0", provided with a handle 0 at one end and a link 0 connected to arm 0 by a universal joint 0. The feed-galley G is provided with a block G connected to a suspended weight O for advancing the column of matrices. The ejector H is carried by an arm P, pivoted on pin P. 'To the arm 0 is secured a plate 0 carrying a pawl 0 which is normally held against a stop 0 by a spring 0. The pawl engages the curved end of the ejector-carrier P, this curve P being so shaped that as the arm moves in the direction of the arrow, Fig. 15, the ejector is moved against the pressure of its spring to eject the matrix from its carrier, and when moved in the opposite direction after the ejector has been retracted by its spring, as in Fig. 17 the pawl yields, allowing the arm 0 to swing back to initial position without again advancing the ejector. The operation is as follows: The operator, located at the larger end of tube M, turns the handle 0 until the parts assume the position illus-- trated in Fig. 17 with the cam-block O at one extreme of its movement and the matrixcarrier retracted to present its offset end opposite the feeding-galley G, from which a matrix is advanced onto pin E. Upon re- .versing the motion of the handle the camblock is moved to the opposite end of its travel, as seen in Fig. 14, thus advancing the matrix-carrier to the extreme limit of its forward motion and bringing the bottom of the matrix-cavity in true focal relation with the objective. This portion of the groove 0 constitutes the first gage for positioning the matrix, and as the measurement for position is taken from the rear end instead of the face end of the matrix this arrangement affords means for gaging the length of the matrix, as well as the position and dimensions of the character. Again reversing the movement of the handle 0 the matrix-carrier is retracted to the position indicated in Fig. 15, thereby bringing the end surface of the matrix into the focal plane, for which purpose the camgroove again acts as the gage for the second comparison. Afterv the measurements for this position have been completed the handle is again moved to advance the cam-plate, thereby retracting and holding the carrier in the position indicated in Fig. 16 and causing the pawl to engage the curved end of the ejector and advance the latter to discharge the examined matrix into the receiving-galley. A further movement of the handle brings the carrier back to initial position, as in Fig. 17. A pusher R, operated by an arm R on rod R the latter provided with a handle R may be employed for removing defective matrices as they are delivered to the receiving-galley.
